PATCH: 5.0-rc11: Error messages during reboot/poweroff

[ggal625]

Tom,

 

Thanks for a wonderful product.

 

When rebooting or powering off I see the following error messages on the console:

 

  ls: cannot access /dev/hd[a-z]: No such file or directory

 

  /etc/rc.d/rc.unRAID: line 195: echo: write error: Invalid argument

 

These errors are benign but might be alarming to your users.

 

The second error results from issuing a stop command to /proc/mdcmd while the array is already stopped:

 

root@bigben:/etc/rc.d# ./rc.unRAID status | grep State
State: STOPPED
ls: cannot access /dev/hd[a-z]: No such file or directory
root@bigben:/etc/rc.d# echo stop > /proc/mdcmd
-bash: echo: write error: Invalid argument

 

I'd like to suggest a trivial patch to redirect both of these to /dev/null:

There's also a couple of errors coming from ls during boot up.

 

Here's an updated patch:
